The data, which was published by Lord Justice Thorpe, who acts as the Head of International Family Justice for England and Wales, showed there were only three new cases of that type handled by the office in 2007. The following year, the total had risen to 65 but by the end of last year, it had reached 253.

Lord Justice Thorpe said that the matters involved child abduction, adoption and forced marriage and were due, he claimed, to "globalisation, increasing movement of persons across borders, and the ever rising number of family units which are truly international".

It revealed that a specialist unit which it had set up to deal with the problem was getting four calls every day, half of which were turning into new cases.

Of course, it is not only relationships forged by individuals of different nationalities which run into difficulties. However, when these partnerships break down, there is often a natural tendency to return to family and familiar surroundings to recover from any feelings of disappointment or distress.

Where children are involved, such matters become more complicated, especially when one or other partner decides to remove them from the country in which they had been resident.

A country's incidence of these sorts of cases mirror its ties with other states. The Foreign Office cited parental child abductions involving 84 different nations. According to Lord Justice Thorpe's report, Poland, Pakistan and Spain were the three places which featured most frequently in the disputes which came to his attention.

Once removed, children are sometimes only returned after a complex process which can be long and drawn out. There can be serious ramifications for the families concerned, both legally and emotionally.

Taking a child out of the country without the express permission of a court or the other parent can be a criminal offence. No matter how comforting the prospect of returning to one's family overseas might seem once a relationship has broken down the consequences need to be seriously considered.

Sadly, my workload and that of other family lawyers specialising in these cases shows no sign of letting up, regardless of the legal and personal consequences. If anything, the increasingly common nature of international partnerships makes further rises likely.

Given the prominence of Poland in figures from both Lord Justice Thorpe and the Foreign Office, it will be interesting to see whether allowing two other East European countries - Romania and Bulgaria - to live elsewhere across the continent without limitation will further fuel the number of international family units living in Britain and the terrible complications of their breaking apart.
